Doposud provedeno bez úspěchu
The vehicle was in a workshop about 30 000 kms ago to have the engine repaired due to a skipped timing belt. Shortly after this repair the problem appeared. In our workshop we verified dynamic compression with current and a pressure transducer, inspection of the timing system and function of the camshaft phaser - timing is incorrect. This is probably due to a worn timing chain. The spark plug gap was verified and we measured a value of 0.7 mm instead of the specified 1 mm. Inspection of the ignition system with an inductive sensor. The spark burning is not stable and the burning time is around 1.5 ms.
